INTEGRATED CIRCUIT DEVICE INTERFACE WITH PARALLEL SCRAMBLER AND DESCRAMBLER

摘要

An interface for an integrated circuit (IC) device. The interface includes a scrambler to combine a plurality of plaintext data streams and a pseudorandom key sequence. The scrambler includes a pseudorandom number (PRN) source and a combiner. The PRN source provides a pseudorandom number. The pseudorandom key sequence is based on the pseudorandom number. The combiner receives the plurality of plaintext data streams in parallel and output a corresponding plurality of ciphertext data streams in parallel to another IC device interface. The interface also may include a descrambler to separate a pseudorandom key sequence out of a plurality of parallel ciphertext data streams. By scrambling plaintext data streams and descrambling ciphertext data streams in parallel, the data transmission rate on the IC device may be slower than a data transmission rate used to transfer data between IC devices.
